接口 ScriptFactory

方法详细资料

• getScriptSourceLocator

  String getScriptSourceLocator()

  Return a locator that points to the source of the script. Interpreted by the post-processor that actually creates the script.

  Typical supported locators are Spring resource locations (such as "file:C:/myScript.bsh" or "classpath:myPackage/myScript.bsh") and inline scripts ("inline:myScriptText...").

  返回:

  the script source locator

• getScriptInterfaces

  Class<?>[] getScriptInterfaces()

  Return the business interfaces that the script is supposed to implement.

  Can return null if the script itself determines its Java interfaces (such as in the case of Groovy).

  返回:

  the interfaces for the script

• requiresConfigInterface

  boolean requiresConfigInterface()

  Return whether the script requires a config interface to be generated for it. This is typically the case for scripts that do not determine Java signatures themselves, with no appropriate config interface specified in getScriptInterfaces().

  返回:

  whether the script requires a generated config interface

• getScriptedObject

  Object getScriptedObject​(ScriptSource scriptSource,
                           Class<?>... actualInterfaces)
                    throws IOException,
                           ScriptCompilationException

  Factory method for creating the scripted Java object.

  Implementations are encouraged to cache script metadata such as a generated script class. Note that this method may be invoked concurrently and must be implemented in a thread-safe fashion.

  参数:

  scriptSource - the actual ScriptSource to retrieve the script source text from (never null)

  actualInterfaces - the actual interfaces to expose, including script interfaces as well as a generated config interface (if applicable; may be null)

  返回:

  the scripted Java object

  抛出:

  IOException - if script retrieval failed

  ScriptCompilationException - if script compilation failed

• getScriptedObjectType

  Class<?> getScriptedObjectType​(ScriptSource scriptSource)
                          throws IOException,
                                 ScriptCompilationException

  Determine the type of the scripted Java object.

  Implementations are encouraged to cache script metadata such as a generated script class. Note that this method may be invoked concurrently and must be implemented in a thread-safe fashion.

  参数:

  scriptSource - the actual ScriptSource to retrieve the script source text from (never null)

  返回:

  the type of the scripted Java object, or null if none could be determined

  抛出:

  IOException - if script retrieval failed

  ScriptCompilationException - if script compilation failed

  从以下版本开始:

  2.0.3

• requiresScriptedObjectRefresh

  boolean requiresScriptedObjectRefresh​(ScriptSource scriptSource)

  Determine whether a refresh is required (e.g. through ScriptSource's isModified() method).

  参数:

  scriptSource - the actual ScriptSource to retrieve the script source text from (never null)

  返回:

  whether a fresh getScriptedObject(org.springframework.scripting.ScriptSource, java.lang.Class<?>...) call is required

  从以下版本开始:

  2.5.2
